	* oacc-plugin.h (GOMP_PLUGIN_async_unmap_vars): Add int parameter.
	* oacc-plugin.c (GOMP_PLUGIN_async_unmap_vars): Add 'int async'
	parameter, use to set async stream around call to gomp_unmap_vars,

	* plugin/plugin-nvptx.c (struct ptx_event): Add 'int val' field.
	(event_gc): Adjust event handling loop, collect PTX_EVT_ASYNC_CLEANUP
	events and call GOMP_PLUGIN_async_unmap_vars() for each of them.
	(event_add): Add int parameter, initialize 'val' field when
	adding new ptx_event struct.
	(nvptx_evec): Adjust event_add() call arguments.
	(nvptx_host2dev): Likewise.

	* oacc-host.c (host_openacc_register_async_cleanup): Add 'int async'
	parameter.
	* oacc-mem.c (gomp_acc_remove_pointer): Adjust async case to
	call openacc.register_async_cleanup_func() hook.
	* oacc-parallel.c (GOACC_parallel_keyed): Likewise.
	* target.c (gomp_copy_from_async): Delete function.
	(gomp_map_vars): Remove async_refcount.
	(gomp_unmap_vars): Likewise.
